The Impact of Maternal Sound on Awareness for Pediatric Patients Undergoing Cardiac Surgery

Intraoperative Awareness

Awareness during anesthesia with intraoperative memory occurs when the patient is able to process information and produce specific responses to several stimuli. Anecdotal evidence suggests that children exposed to therapeutic suggestion consisting of gently encouraging, positive words spoken to them during emergence from anesthesia seem to arouse after surgery with less agitation, less pain and lower requirements for pain medications. Therapeutic suggestion has been associated with positive results in some adults during surgery, but it is unknown how therapeutic suggestion affects children. A newborn's recognition and preference for their mother's voice occurs early in life, very likely during fetal development. Additional evidence, revealed that at least as early as 4 months of age, infants process auditory stimuli from their mother's voice at a higher amplitude than they process auditory input from female strangers, suggesting that maternal voice stimuli undergo a unique form of cerebral processing that lends support for the existence of neurophysiologic mechanisms that reflect a child's preference for his/her mother's voice. This study aims to evaluate and compare the possibility of intra-operative awareness prevention by using either music listening or maternal sound listening in children undergoing cardiac surgery.

Anesthesia Depth Increases Delirium Incidence

DeliriumAnesthesia Awareness

This study aimed to determine whether targeting bispectral index (BIS) readings of 55 (light anaesthesia) was associated with a lower incidence of delirium, dementia (POD), POCD and mortality but higher rates of awareness and complications than a standard of care anaesthesia blinded to depth monitoring.

AwarenessAnesthesia2 more

Awareness during general anesthesia - that has an incidence between 0.1% and 0.9% of cases and may be more in elderly - remains a concern for anesthesiologists. Awareness experiences range from isolated auditory perceptions to reports of a patient being fully awake, immobilized, and in pain. The isolated forearm technique allows assessment of consciousness of the external world (connected consciousness) through a verbal command to move the hand (of a tourniquet-isolated arm) during intended general anesthesia.

The aim of the study was to assess the influence of volatile induction of general anaesthesia with sevoflurane using two different techniques and intravenous anaesthesia with propofol on the possible presence of epileptiform electroencephalograph patterns during the induction of general anaesthesia. We aimed to verify whether presence of epileptiform patterns (EPs) defined as polispikes (PS), rhytmic polispikes (RPS), periodic epileptiform discharges (PED) on Electroencephalographs (EEGs) influence the behaviour of values of the Bispectral Index (BIS), State (SE) and Response (RE), A-line Auto Regressive Index (AAI) derived from middle latency auditory evoked potentials (MLAEP) during the induction of general anaesthesia using abovementioned techniques and such variations may be useful in detection of presence of EPs.

Awareness During Blended Anaesthesia

ConsciousnessLevel Depressed1 more

the aim of this study was to estimate the relations between Bispectral Index values and explicit or implicit memory or dreams during two different minimal alveolar concentration (MAC) of sevoflurane in patients undergoing blended anaesthesia for major abdominal surgery and ,in this way, estimate the possibility to reduce, in presence of a deep analgesia, like epidural analgesia, the requirement of halogenated volatile anesthetics.

The Incidence of Intra-Operative Awareness in China and Analysis of Relevant Factors: a Multicentre...

Intra-Operative Awareness

Medical literature about awareness during general anesthesia is rare in China, and some small sampled studies in China showed a significantly higher incidence (1.5~6%) of intra-operative awareness compared with western countries. The investigators sponsored this multicenter, large sampled, prospective study to determine the incidence of intra-operative awareness in China, and the preservation effect of BIS monitor on the incidence of awareness.

Glasgow Coma Scales and General Anesthesia

Anesthesia Awareness

The study evaluates the general anesthesia management with BIS monitorization in terms of hemodynamic stability, drug concentrations and drug consumption in patients who underwent surgery due to intracranial pathology and who were divided in three different GCS groups.
